Description
Technical field：
The present invention relates to technical field of composite materials, and in particular to a kind of fibrous composite for athletic protective and its
Preparation method.
Background technology：
Carbon fiber, is high intensity, the new fiber materials of high modulus fibre of a kind of phosphorus content more than 95%.It is by
The organic fibers such as flake graphite are piled up along fiber axial direction to be formed, through microlite obtained from carbonization and graphitization processing
Ink material.Carbon fiber " soft outside but hard inside ", quality is lighter than metallic aluminium, but intensity is higher than steel, and with corrosion-resistant, high-modulus
Characteristic, be all important materials in defence and military and civilian aspect.It not only has the intrinsic intrinsic property of carbon material, has both again
The soft machinability of textile fabric, is reinforcing fiber of new generation.
And carbon fiber is frequently utilized in sports equipment in the prior art, its intensity and light feature are considerably increased, still
Its price is high, it is used and not bery strong the features such as some fields are not easy to process and are combined.The material of athletic protective is general
It is that, for the helmet, knee-pad, shell of moving component etc., these materials not only require nothing more than its intensity will height.But also to meet tool
With certain elasticity, it is not easy to broken rotten, and the characteristics of to keep lightweight, and these materials of the prior art are typically all
The common plastic material used, hardness is higher, it is necessary to increase very thick soft dottle pin, fragile rotten, once with hard
Object is hit, and is easier to split into several valves, and human body is caused damage, and desired thickness is thicker, heavier-weight.
The content of the invention：
The technical problems to be solved by the invention are to overcome existing technological deficiency high there is provided a kind of intensity, elastic good,
Do not allow frangible rotten, protection effect good, and it is lightweight for fibrous composite of athletic protective and preparation method thereof.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of fibrous composite for athletic protective, it is characterised in that：It is made up by weight of following components raw material,
It is preferred that be made up by weight of following components raw material, 25 parts of polyurethaneurea elastic fiber, 9 parts of carbon fiber, it is unsaturated
3 parts of 1000 parts of resin, 3 parts of sodium carboxymethylcellulose, 5 parts of casein glue, 3 parts of stabilizer, 3 parts of catalyst and pigment.
A kind of preparation method of fibrous composite for athletic protective, it is characterised in that：Comprise the following steps,
1), weave, be respectively prepared using polyurethaneurea elastic fiber and carbon fiber it is thread, then by thread polyurethane-urea
Elastomer is into latticed with carbon fiber interlacement weave, is set wherein thread polyurethaneurea elastic fiber and carbon fiber is interlaced
Put；
2), melt, unsaturated-resin is heated into 55~65 DEG C softens 25~35 minutes, then adds pigment, carboxymethyl
Sodium cellulosate is thoroughly mixed, then heating is melted, and is at being incubated under molten condition, the viscosity control under molten condition
In 10000~20000CPS；
3), immerse, first add stabilizer, add catalyst and casein glue and be sufficiently mixed respectively, then will be woven
Latticed urethane urea elastomer and carbon fiber, which are uniformly conveyed and be immersed in unsaturated-resin, to be slow transitted through；
4), extrude, by the carbon fiber wire material after immersion by mould extrusion molding, then curing molding；
5), cool down, the temperature of the product after solidification is cooled to normal temperature.
Described unsaturated-resin is thermosetting resin, and temperature control during curing molding is between 130~140 DEG C.
Described catalyst is made up of following components raw material by weight, 8~10 parts of copper of hydrogenation, 5~7 parts of caustic alcohol and fluorine
2~4 parts of silicic acid.
Described stabilizer is made up of following components raw material by weight, 20~30 parts of diacetyl and caffeic acid 1~1.5
Part.
Described unsaturated-resin is one in phenolic resin, epoxy resin, unsaturated polyester resin and polyurethane resin
Plant or a variety of.
The sodium carboxymethylcellulose of the present invention can increase the viscosity of the unsaturated-resin under melting, make its unsaturated-resin
It can completely stick on the fiber mesh of braiding, and can prevent the unsaturated-resin under molten condition from occurring what is flocculated
Situation, is easy to follow-up immerse and extrusion molding.
The casein glue of the present invention can prevent the unsaturated-resin of melting from suddenly encountering the low braiding of temperature when immersing fine
Brittle membrane layer is quickly formed in the surface unsaturated-resin temperature rapid decrease of braided fiber grid during dimension grid, can
Ensure seamless compound between braided fiber grid and unsaturated-resin, be conducive to increasing the intensity of product.
The present invention can be according to the different resins of selection, and are manufactured into various types of protective materials, these protective materials
Hardness strength and elasticity etc. can be carried out appropriate selection, fiber mesh of the invention may be arranged as multilayer, extrusion
Various three-dimensional structures, and different products can be extruded according to the shape of extrusion die.The present invention can also be by pouring
Mode be molded the product of solid shape.
The stabilizer that the process that the present invention is also produced in material is added in stabilizer and catalyst, the present invention can be played
Stable unsaturated-resin melts the stability of state, that is, is kept molten by the viscosity of lower unsaturated-resin, adds catalyst
With certain solidification, it is easy to the progress of next step to be molded, is conducive to shaping solidify afterwards to be quickly hardened.The present invention is in shaping
When first add stabilizer and add catalyst, can open prevents catalyst from carrying out excessive interference to stabilizer so that stabilizer
With more preferable stability, the present invention is molded immediately after catalyst is added.
The stabilizer and catalyst of the present invention is all to mix compound stabilizer and catalyst, compared to traditional stabilizer
There is better performance with catalyst.
Thermosetting resin typically is used in the present invention, is conducive to the section bar that molding structure is complex, and for heating
It is no longer reversible after solidification, as both not dissolving, and it is non-fusible, it is processed into section bar more particularly suitable.
The beneficial effects of the invention are as follows：The intensity of product produced by the invention is high, and elasticity is good, it is not easy to broken rotten, protection effect
It is really good and lightweight, human body is had no side effect.
